000 AXPZ20 KNHC 010131 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0100 UTC Fri May 1 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N77W to 07N84W to 07N102W. The ITCZ extends from 07N102W to 06N126W to 06N134W. Scattered moderate convection is noted from 03N to 10N between 79W and 106W and from 02N to 07N between 136W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A cold front that moved through the Gulf of Mexico this evening is causing strong N gap winds in the Gulf of Tehuantepec. Elsewhere, high pressure centered near 30N135W extends a ridge SE to just S of the Revillagigedo Islands. Moderate NW winds are occurring W of Baja California Norte, with light to gentle winds elsewhere. Moderate NW swell propagating into the waters offshore Baja California Norte is bringing seas of up to 8 ft, and these will continue into Fri before the swell decays. Smoke from agricultural fires lingers over the waters from Cabo Corrientes SE to the Tehuantepec region. Note that smoke may reduce visibility at times over these waters. The offshore high pressure ridge will persist through early next week. Near gale force northerly winds are expected in the Tehuantepec region tonight through Fri. A set of NW swell will likely impact the waters north of Cabo San Lazaro Sun night through Tue night. Smoke from agricultural fires may reduce visibility at times in the offshore waters south of Cabo Corrientes. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Generally gentle flow prevails over the region due to a weak pressure gradient pattern. Seas are 4 to 6 ft. Smoke from agricultural fires is present over waters off Guatemala and El Salvador. Fresh to occasionally strong gap winds will pulse in the Papagayo region through Mon. Smoke from agricultural fires in Central America may reduce visibility at times in the waters off Guatemala and El Salvador. REMAINDER OF THE AREA... A ridge extends across the northern waters from high pressure centered near 30N135W. Moderate to occasionally fresh trades persist west of 125W, especially closer to the ITCZ, with mainly gentle winds elsewhere. Latest altimeter passes reveal seas are 8 ft or less across the basin, although W of 130W and just N of the ITCZ, some 7 to 9 ft seas will occur at times through early next week. High pressure will persist across the northern waters through early next week. NW swell moving into the waters west of Baja California will build seas to 8-10 ft east of 125W by early Fri. Looking ahead, winds and seas may increase west of Baja California early next week as high pressure builds NW of the region. $$ KONARIK
